A' application med september 9, y1926..- serial :No.l 134,410.1,

This .invention relates to `'sanitary *face pads, `and particularly `to a p ad to cover the 1;. frame inwhich the patients face 1s placed nating contact of the patients face therewhen the eyes are being tested.

.i The prime `object of the the invention 1sy tov design a sanitary pad, which can be quicklyapplied to j and removedy from the frame, which completely protects the patients-face from Contact with any part of the said frame.

Another obj ect is to design a pad'provide with integral strips for holding it in position, together with a projecting section adapted to cover the adjustable chin rest.

A further object is to provide a simple and convenient pad which is easy to make, and which can be packed in bundles or cartons for shipment and distribution.

The above and other objects will appear as the specification progresses, reference being had to the accompanying drawing in ywhich I have shown the preferred embodiment of my invention, and in which like reference numerals indicate like parts throughout the several views thereof.

In the drawing:

Fig. 1 is a front view of the pad formed to shape.

Fig. 2 is a front view of the frame showing my sanitary pad in place thereon.

Fig. 3 is an edge view thereof.

Fig. 4t is a sectional view of the adjustable chin rest, and

Fig. 5 is an enlarged transverse sectional plan view of one of the side bars of the frame illustrating the pad covering.-

Where a large number of people must place their face in the same identical frame, a sanitary problem is immediately present, due to the fact that in warm weather the patients perspire freely, and when the frame is damp, dust and foreign matter will adhere thereto, and no patient cares to thrust his' or her face into a frame on which the perspiration from another patients face has been deposited, even though it is wiped clean with a cloth each time.

In cold weather the frame is cold making it disagreeable at this time of the year, and I have therefore designed a santitary pad which completely covers the frame and allows for adjustment of the chin rest, elimiwith, and which canbe vdiscarded anda fresh padused for eachpatient. 1 I f Referring now particularly tothe drawing, the numeral 5 vindicates. the` frame or face restA of aconventional opticalmachine, such as usedby eye examiners for.l testing the` eyes. This ismountedfon a post 6, and

g 1,648,315 l g a chin rest 7 i isy adjustably moimted fin said,y post, projecting therefrom as clearly shown in Figs. 2V and 3 of the drawings.

The pad comprises a sheetV of paper or similar material 8, shaped to cover the edges of` the frame as clearly shown in Fig. 1y

of the drawing, and having a centrally disposed opening 9 to accommodate the patients face, a small lip 10 being formed on f the upper end, and an opening 11 is punched therein, and through which the pin 12 is inserted for securing the pad in place.

The lower end is formed with arounded section 13 adapted to cover and fit in the adjustable chin rest 7, and in which .theV

patients chin rests. Strips 14 .and 145L form 7 a part of the pad, andare used for securing the lower end of the pad in position, the inner edges being, cut away as shown at 15 to allow the operator to wrap them around the rib 16, which is formed integral with the chin rest, for holding the bottom o f thek pad in position. l

This pad can be formed from a thin sheet of absorbent paper or other suitable material, and may 'be moulded or pressed to shape, I find however that it is economical lto v shape it from a flat sheet, leaving sucient y stock to cover the frame, and when the patients face is inserted, the pad easily conformsto the contour thereof, -and I donot wish to'be limited to any Vspecific manner or method of forming the pad.Y

In practice the patient is seated'in the.

chair used for the purpose, the operator raises the member 12, places the top of the pad so that the pin engages the opening 11, holding the upperend of the pad in position, Vhe then grasps the strips 14:` and 14a crossing them around the rib 16, the opening 15 permitting this winding action, and theV After the test is comv pad is in position. pleted, it is removed and a new pad attached, the fact that the chin rest projects atan Vangle to the frame permits of the vertical adjustment thereof without affecting the pad,

as any excess stock is taken up in this bend. From the foregoing description it will be obviousthat I have perfected a very simple,

and economical sanitary pad-.fonoptieal ina- ,l v
